Title: Recording and reproducing device, reproducing device, failure detection method, and program
Inventor: TERADA AKIO
IPC: G11B7/004
Filed: 2007-10-03
Abstract: <P>PROBLEM TO BE SOLVED: To precisely discriminate between a failure of a device and a failure of an optical disk.  <P>SOLUTION: In a step S1, an evaluation part evaluates a reproduction operation of each channel of a recording and reproducing device. In a step S2, a detection part determines that a failure occurs when abnormality is detected in the reproduction operation of at least one channel, and the process proceeds to a step S3. In the step S3, the detection part determines that the failure occurs in the channel with the detected abnormality when the abnormality is detected in only one of the channel A or the channel B or when the abnormality is detected in both the channel A and the channel B but the contents of the detected abnormality are different from each other, and determines that the failure occurs in the optical disk when similar abnormality is detected in both the channels. The present invention may be applied to an optical disk drive, for example.  <P>COPYRIGHT: (C)2009,JPO&INPIT
